i ing drawingsywhich form a part of my V.pecificatio-n. Y

My invention relates to a device more` especially adapted for drilling a single holeof any desired size, at each operation, in railroad rails; the device consistingof a truck portion ada ated to travel alonn'lthe rails` of a railroad and power-driven when desired; it also comprises drill holding` and operating mechanism so secured tothe truck-frame as to swine* to the outside of the rail when in operative position and to fold upward, over the truck. 4when in transporting or inoperative position. n

The device contemplates means whereby the motive power of the truck may be ernployed for the `drill-mechanism; together with means whereby the drill mechanism v will be properly secured to the rail to be operated on and the drill-.bit rand .operating mechanism maintained in proper alignment during; the operatingn movement of the drill mechanism toward therail. v

The invention also contemplates means whereby the operation of the vdrill mechanism, the positioning of the drill and transmission of power to the drill-mechanism are operable and controllable from the drill side of the device; while at v`the same time contemplating' a `construction wherein an adiustn'lent of bit is obtained `by means of a hand-operated crank Aon the drill side of the device. My invention also `contemplates a construction adapted to drill holes in the rail-web at any' desired pointrelative to the base of the rail,y by the mere adjustment of adjustable elements or rests ony the drillframe. f

rllhe objects and advantages of my iiniuovefl device will be more fully' compreheuded fromthe following detailed description of the drawings` wherein i lfirure 1 is a side elevationof my improved device illustrated in operative position on the rails, with the drill-bit in penetrating position.

Figure 2 is an end elevation of the drill side of the device with portions ofthe frame and elements broken away. .y

Figure 3 is an enlarged side elevation and longitudinal sectional view of the drilling,` mechanism orportion of the device.

Figure 4 is a top plan View of the'mechanism shown i in Figure 3 with portions broken away to disclose other features or elements therebeneath.

ln the particular exemplific'ation ofmy invention, it comprises a suitable truck-` frarne 10 provided with suitable liournals for `'the track-wheels 11'; the truck-frame being provided with a transversely disposed member 12, the outer ends whereof are provided with suitable stub-aigles or journals to re.- celve the wheels 13 adapted to travel along the adjacent rail. The truck-frame is preferablv shown provided with a suitable interl f' nal combustion motor, as at 14:, the cranlishaft whereof may beplacedinto operative relation with one 'of the truck-wheels so as to employ motive power for transporting the truck or device along the rails when desired as for example by chain and sprocket as shown fin mv cri-pending application Serial -No 348,002.l One side of thetruclr is pro-- vided with ground-engaging Wheels, as. at 15, mounted on a suitable shaft supported by links 16 and 17A; thelinlr 16 being pivotally secured at 18 tothe truck-frame while the link 17 lis shown pivotally secured at 19 to bell-crank 20, which latter is pivotally secured to the truck-frame iand venables .the shaft carrying the ground-wheels 515 tobe raised or lowered into or out of ,ground-en- .i

gaping position through the oscillation of bell-crank 20, which isadapted `to be controlled by mechanism later to be described.

The ground-wheels. 15 are disposed at right angles tothe main frame,`as clearly shown in Figure 1, andA therefore atright With i this angles to the truck-wheels 11.

'construction it is' evident .that when the ground-wheels are lowered from the position shown in Figurefl, the opposite or drilli mechanism carrying side of the device mayl be lifted from the track and enable the device to be transported or moved'away from the rail; it being understood, of course7that when it is desired to move the ldevice awayV from the rails, the drill mechanismcarrying portion of the frame is thenfolded up over the main or truck portion of the device, in a manner similar to that shown and described in my copending application Serial No. 348002.

rlhe transversely disposed portions l2 oit the main frame o'i the device are provided at suitable points with brackets or journalboxes, as at 21, for oscillatingly securing` the 'frame 22 oi' the drill mechanism to the main trame oit the device. rlhe pivotal mountingr or' the drill-traine preferably consistsin a rod or member disposed through the brackets or journal-boxes 2l secured to the main frame members 12at opposite ends of the device; With the drill-frame members 22 firmly secured or clamped to a journal or rod and ata point intermediate of the main trame members l2 at opposite ends of the device. rlhe journal, disposed through the brach' i' or journal-boxes 2l, at points coincident with the points Where iframe mem- *bersv 22 are secured thereto, is preferably provided With segmental grooved Wheels adapted to rotate with the onrnal member. The grooved segmental Wheels 23, each have one end of the segment provided with chain 2li, Whose tree end has a coil. spring' secured thereto; While the latter, "in turn is secured at a proper point to the main trame iQ the device. `The springs 25 are intended to constantly exert a pulling` tension on the chains 24 and therefore on'the seg-y mental Wheels 23, so that the drill-frame 22 Will at all times be more or less yieldinpjly suspended in either position, due to the pulling'tension of' the springs 25 exerted on the segmental Wheels.

The Outer ends of the gournal member, whereby the drill-trame is oscillatingly supported' on' the main frame, is preferably provided Vivith crank-armadas shown at 26, to which suitable cables or rods 27 are secured; the cables or connecting means 27 being also; secured to the ends of the belloranks 20. With this construction, it is ap- 'parent that when the drill-.trame 22 is elevated or sivung over onto the main or truckl trame. thereby oscillating' the crank-arms 2G in a direction toward the ground-'wheel side of the device, that the connecting;Y means will be. slackened so as to permit the lgroundivheels to drop to grouiid-engaging` position.

.fis the construction ot themain or truckframe, the ground-Wheel mountingl and controllingmechanism and the mounting` of the drill-trame portion oit the device, :ire all identical with said elements. their construction and operation as shown and described in my copending application. more minute description and statement oi' operation need not be here entered into; because in practice the drill-frame and mechanism of' the presont construction is adapted to be bstituted :for the drill-frame and drilling mechanism shown and described in my copending application; such substitution being readily accomplished through the mere removal oit the brackets or journal-boxes 2i andthe snpporting journal provided with the grooved segmental Wheels 23; at the same timethe outer sectiony of the drive-shaft is removed and replaced by the outer drive-shaft section 28, more clearly disclosed in Figure-3; this outer drive-shaft section, like that disclosed. in the copendinp'.application, being secured to the inner sections of the drive-shaft, by suitable universal joint at a point in alignment with the pivotal.` point oiE the drilltrame von. thel main or truck-trame.

The outer drive-shaft section 23 is provided with a sprocket-Wheel 29 adapted to receive sprocket-chain 30 which latter is disposed about a sprocket-Wheel 31 which is slidingly mounted on a shaft 32 but adapted to transmit rotation thereto, end of the drive-shaft 28 is supported by vmeans ot a suitable'bracket 33, the lower ends whereof are suitably clamped onto the drill-frame members 22, see Figure Ai. The sprocket-Wheel Si is 'maintained in vertical. alignment with sprocket 29 byv means or bracket 33, which is provided with a transversely disposed portion at the bottoni adapted to take up against the hub ot the sprocket 3l; While the opposite end oi the hub ot the sprocket takes against the transversely disposed bracket or straps 34C which are clamped to the parallelly disposed drillframe members 22. /The sha-tt is provided ivith a gear .35 which meshes With a 36' securedlto the drill-spindle 37. The gears 35 and 36 are enclosed in suitable casing; or housing 38 which is provided With tapped portion adapted to receive screw-rod 39, see Figure 3. rlhe screw-rod 39 is provided with a gear Ai() yshoivn in meshing* relation with `a. pinion il which is secured against rotation'on hand-operated shaft or crank 4-2; the shaft or crank being rotatably mounted on a suitable Jframe orcastinn; 43. 'Y

The casting i8 is socketed to receive the end ot the screw-rod 39; the latter' being provided with an miler-gement or tiann'c, as at 4:4-, ivliichivill. prevent longitudinal movement otrod 39 relative to casting; 3; With the result that rotation o'ti'od will cause the gear-housing or casing 38 to travelA lengthwise ot screw-rod 39 thus enabling: the housing or casing' 33, with. the drillspindle 3'?, to l e adjusted relativeto the rail .so as to coniipeusate tor drill-bits ot diilei'- ent lengths.

'The housingl or casing; 38 formed to receive suitable ball or anti-friction bearings,

as at 45, adaptedjto take up the end thrust on the drill-spindle.

1ii/lith the construction ot housing, thev gearing` and bearings may lbe constantly maintained in a. suitable state ot lubrication The gearehousing or casing 38 is providedv at opposite sides Vand both ends with lugs,

as shown at 38a, which are apertnred to receive the frame members22 so as to permit the housing or casing to slide lengthwise of the frame-members. The transverse bottom `portion of bracket 33 will preyent the too far forward movement of the housingor casing; while suitable stops at the ends of the trame-members,- as shown at 46, will prevent said housing from moving too 'tar backwardly.

The normal relation between the rear end of the housing or casing 38, and the transverse portion of bracket 33 is such as to permit a predetermined amount `ot Iforward movement of thefhousing,` or casing, as is evident from the construction as illustrated in Figures 3 and 4.

The casting 43 is provided with rearwardly disposed apertured lugs 4? (see Figures 2 and 4) which provide suitable bearings for a rotatable shaft 48. This shaft 48 is provided at a suitable point with spaced flanges 49, notched as shown in Figure 3 to receive the latch mechanism or dogar carried by lever i 50, whereby controlling relation between the lever and theshaft may be effected so as lto enable the operator to rock shaft 4S in the desired direction to actuate the elements now to be described. The outer ends otshatt 48 are provided with suitable crank-arms 5l, rigidly secured'thereto; and these arms 51 have a shaft 52 loosely mounted therein. The ends of shaft 52 are provided with crank-arms 53, one of which terminates in a lever 54.

y The free ends of the crank-arms 53 have,

the ends oi feed-hooks 55 pivotally secured thereto by means of stud'bolts 55. The feedhooks 55 extend forwardly and are adapted to contact with lthe opposite or inside of the rail, a distance below the horizontal plane ot drill 57, substantially equal to the distance of the pivot points 56 from or below the `center ot the ulcruin point of feed-lever- 50,*namely the center of shaft 48. thereby providing' a straight drilling feed-thrust which eliminates all unnneeessary friction and at the saine time permits proper and true operation of the drill.` The 'Feed-hooks are shown provided with clips 58 through which rod 59 extends: the rod extending transversely oit the device so as -to be dis-4 posed through the clips 59 on both feedhooi-s 55 arranged at opposite ends ol the machine. The rod 59 is threaded at its ends and provided with nuts whereby the clips 58 are ri lv clamped at the desired point on the hoois rihe rod 50 is also provided with guides loosely mounted on frame members; 22 and rod 59 seri/'es to hold thel hooks in proper alignment.

Each crank-arm 5l has a rod 6l pivotallv secured on the inner side thereof; the rod 6l being,r bent tor extend over shaft`52 and thence lback into-substantially the same horizontal` plane the pivotal points thereof yon crankas shown in Figures?) and 4. The

arms 5l,

forward ends of the `rods (il are slidably mounted in lugs on the sides of casing 38,

whereby the rods are supported inproper horizontal position when'tlue` mechanism is in operative position. The forward ends of the rods 6l are shownthreaded and provided with adjustable heads or tips`62i`so as to permit the tips to be adjusted lengthwise ot' the rods '6l and adapt `them to a long?v or short drill-bit; the-tips 62 being locked in adjusted position by means of a nut 63. The

rods Glare intended to have approximately..

lthe saine length ot strolre the drill, but are arranged to move in the opposite diret:n

tion so as to push against the rail when the f drill is being withdrawn. from the drilled hole in the web ol the rail. i

The crank-arms 5l are shown provided with laterally disposed lugs 54 on l'the sides to which the crank are secured; and these lugs 64 are provided with adiustablc setscrews 65u Theset-screws 65 are .intended to control the limit of movement ot' cranks when in operative yposition and alsotocontrol'the len gtli ot drill-stroke; the set-screws 65 controlling` the ters of studbolts the pivotal point ot cranks and"therefore of lever 54l (which -is integral with one ot sai'd` cranks) downwardly, thereby' movingy the-*tree end of cranks with the stud-bolt 46 into Contact with set-screws 65, whereby the feed-hooks 55 will be retracted and the `hook-ends thereof brought into` .clamping engranerr-.entA with the web of the` rail on the 'side opposite to that ot the drills. 1lplli'th the teedfhoolrs positioned as just described, the pressure en rted bv the operator on. lever 50 (such 'fori' l.rd pressure having" a tendenc.T to induce furthe recitingoft' shaft't 48 iny a direction tendine* to swine the v'tree ends of cranks 5l `tui to the rigjjht in Figure 3) tends to tone 'the drillnfiechaey msm. namely the casing or housing 38 w :h the `drill 57 toward the rail: theV forward pressure beingr mainained until the drillinfr operation is completed,l as shown in Figiure 3. i Y
